Study summary

The purpose of this study is to identify potential risk factors for and determine the rate of pathological fracture for patients which having spine metastases from breast cancer and be defined as potentially unstable (SINS 7-12) according to the Spinal Instability Neoplastic Score (SINS). The investigators' analysis will provide robust data about the development of spinal instability and help identify the optimal timing of local surgery treatment.

Read the detailed description

Considering the concept of spinal instability remains important in the clinical decision-making process for patients with spine metastases, the Spine Oncology Study Group (SOSG) devised an 18-point SINS, which proved reliable and has been widely used in clinical practice. Scores of 0-6, 7-12, 13-18 are considered stable, potentially unstable, and unstable, respectively. Lesions with a low SINS (score 0-6) do not requires surgical interventions, whereas a high SINS (score 13-18) predicts the need for surgical stabilization to restore spinal stability. However, treatment strategy of intermediate SINS (score 7-12) lesions remains ambiguous owing to the uncertainty of spinal stability. With the duration of spinal metastases, some potentially unstable lesions turn to be stable while some turn to be unstable, and several factors such as tumor involvement for vertebral body, radiotherapy may account for different outcomes. Owing to the relatively weaker growth and invasion ability of breast cancer cells compared to other solid tumors such as lung cancer and liver cancer, patients with breast cancer and spinal metastases have longer life expectancy. Reasonable and prompt local surgical intervention to restore spinal stability can achieve pain relief and better quality of life effectively. Moreover, most spinal metastases from breast cancer show lytic or mixed lytic-blastic bone lesions, which exacerbates the spinal stability and results in pathological fracture. Thus, investigators focus on patients which having spinal metastases from breast cancer and an intermediate SINS (score 7-12) to explore the rate of pathological fracture and relevant risk factors. This study will help spine surgeon to identify who could benefit from a prophylactic stabilization procedure with high risk of pathological fracture and when is the best timing of surgery.

Study population

A total of 120 patients with potentially unstable spinal metastases of breast cancer will be enrolled

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Age 18-65 years, female
  • Had a histological confirmation of breast cancer, including all pathological types
  • Had a histological or radiological confirmation of spinal from breast cancer
  • SINS 7-12

Exclusion criteria

Exclusion Criteria:

  • Prior prophylactic stabilization surgery to the spine at current level of interest
  • Patients with other except breast cancer
  • Misdiagnosis of spinal from breast cancer confirmed by pathological examination
  • Patients without undergoing follow-up on schedule
  • Withdraw from the study for any reason
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Rate of the pathological fracture of spine

    Pathological fracture will be detected using Magnetic Resonance Imaging (MRI)

    Time frame: First diagnosis of spinal metastases, every 3 months in the first year after diagnosis, every 6 months after one year after diagnosis. Up to 2 years

Secondary outcomes

  1. Quality of life outcomes measured by EORTC QLQ-C30 questionnaire

    Time frame: First diagnosis of spinal metastases, every 3 months in the first year after diagnosis, every 6 months after one year after diagnosis. Up to 2 years

  2. Quality of life outcomes measured by EORTC QLQ-BM22 questionnaire

    Time frame: First diagnosis of spinal metastases, every 3 months in the first year after diagnosis, every 6 months after one year after diagnosis. Up to 2 years

  3. Pain and functional outcome data measured by Brief Pain Inventory (BPI) questionnaire

    Time frame: First diagnosis of spinal metastases, every 3 months in the first year after diagnosis, every 6 months after one year after diagnosis. Up to 2 years

  4. Spinal stability measured by Spinal Instability Neoplastic Score (SINS)

    The Spine Instability Neoplastic Score (SINS) is a comprehensive classification system that can aid in predicting spine stability of neoplastic lesions. The 18-point SINS includes global spinal location of the tumor (score 0-3), type and presence of pain (score 0-3), bone lesion quality (score 0-2), spinal alignment (score 0-4), extent of vertebral body collapse (score 0-3), and posterolateral spinal element involvement (score 0-3). As the SINS increases, the spine stability of neoplastic lesions turns to be worse

    Time frame: First diagnosis of spinal metastases, every 3 months in the first year after diagnosis, every 6 months after one year after diagnosis. Up to 2 years

  5. Neurologic outcome measured by Frankel grading system

    Time frame: First diagnosis of spinal metastases, every 3 months in the first year after diagnosis, every 6 months after one year after diagnosis. Up to 2 years

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Dec 2017 (actual). Primary completion is estimated for Dec 2022, 60 months after the start.

Of 1,191 non-industry observational studies under Breast Neoplasms, half reached primary completion within 58 months of starting (the median), counting those still running; a quarter within 25 and three quarters within 139. This study's planned 60 months is close to that.

Counting every sponsor, half of 1,380 studies reached it within 55 months; a quarter within 25 and three quarters within 126.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 8, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
